A gamma voltage generator, a display device, and a driving method of a display panel. The gamma voltage generator includes a control module, a data storage module, a digital-to-analog conversion module, and an output module which are electrically connected in sequence. The data storage module includes at least a first data memory and a second data memory. The first memory is configured to store and output a first digital signal to enable the output module to output a first gamma voltage in a first operating phase of the display panel. The second memory is configured to store and output a second digital signal to enable the output module to output a second gamma voltage in a second operating phase of the display panel. The first operating phase and a second operating phase are divided in accordance with a chronological order.
Legal claims defining the scope of protection, as filed with the USPTO.
6. The driving method of the display panel according to claim 3, wherein an operating time period of the sample panel is divided into the first time period, the second time period, and the third time period in sequence in accordance with the chronological order.
7. The diving method of the display panel according to claim 6, wherein the operating time period of the sample panel is divided by time nodes, the time nodes are determined based on a debugging parameter of the gamma voltage under a case in which both a display luminance and a color gamut of the sample panel are kept unchanged, and the debugging parameter comprises debugging times or a value of a debugged gamma voltage each time.
8. The diving method of the display panel according to claim 1, wherein the sample panel has the same structure and functions with the display panel.
9. The diving method of the display panel according to claim 1, wherein the gamma voltage is debugged with a preset period to enable the sample panel to reach the target luminance.
15. The driving method of the display panel according to claim 12, wherein an operating time period of the sample panel is divided into the first time period, the second time period, and the third time period in sequence in accordance with the chronological order.
16. The diving method of the display panel according to claim 15, wherein the operating time period of the sample panel is divided by time nodes, the time nodes are determined based on a debugging parameter of the gamma voltage under a case in which both a display luminance and a color gamut of the sample panel are kept unchanged, and the debugging parameter comprises debugging times or a value of a debugged gamma voltage each time.
17. The diving method of the display panel according to claim 10, wherein the sample panel has the same structure and functions with the display panel.
18. The diving method of the display panel according to claim 10, wherein the gamma voltage is debugged with a preset period to enable the sample panel to reach the target luminance.
